The Boulder-based brewery had to change the beer name from Brett on the Broncos[3] to “Omaha! Omaha! Brett,” after receiving a “cease & desist” letter from the magnanimous NFL[4].

Brett on the Broncos — a name offered by West Flanders Brewing was banned by the NFL.

The letter said the brewery is “engaging in unauthorized promotional use of the NFL Marks … including the AFC word mark and the Denver Broncos[5] word mark and color combination.” Who knew the NFL had rights to orange and blue. Someone should tell God next time he tries one of those sunsets.

The brewery had announced the beer Wednesday, only to receive the letter one day later.

The plan was to tap the “AFC Champion Style Ale” on Thursday as part of its weekly single keg series in honor of Sunday’s AFC Championship Game[6].

“It’s our Obfuscation Trippel blended with a special batch of our Angry Monk Belgian-style golden ale that was fermented with a Brettanomyces yeast from Belgium’s famed Lambic region,” the brewery said in a press release on Wednesday.

The new name for the beer is a reference to the play call[7] that Broncos’ quarterback Peyton Manning is known to shout dozens of times at the line of scrimmage. But it is not clear whether the NFL has rights to the name of the Nebraska town just yet.
